Specmcation of Letters Patent.

Patented Dec. 28 1915.

Application filed June 23, 1915. Serial No. 35,863.

To allwhom it may 00mm Be it known that I, WALTER C. Bo'r'r, a

citizen of the United States, residing at Walla Walla, in the county ofWalla Walla and State of Washington, have invented new and usefulImprovements in Wrenches, of which the following is a specification.

The present invention relates to improvements'in wrench construction, anobject being to provide a simple comparatively cheap I and thoroughlyefficient wrench which is primarily adapted to retain a nut so that thesame may be screwed upon a bolt.

With the above and other objects in view,

the improvement resides in the construction, combination and arrangementof parts set v forth in the following specification and falling withinthe scope of the appended claims.

In the drawings: Figure 1 is a plan view "of a wrench constructed inaccordance with the present inventlon, Fig. 2 1s a transverse sectionalview approximately on the, line 2-2 of Fig. 1, Fig. 3 is. a sectionaltiew approximately on the line 33 of Fig. 1, Fig. 4 is a plan viewlooking in an opposite directionfrom that shown in-Fig. 1, Fig. 5 is ahorizontal sectional view approximately on theline 55 of Fig. 2, Fig. 6is a perspective View of one of the arched members and 30 similar Viewof the head of the wrench. VF-ig. 8 is a detail the jaw carried thereby,and Fig. 7 is a perspective view of one of the dogs.

Inthe drawings, I construct' a wrench which includes a handle. 1 havingone of its ends provided with a'flat round portion 2,

the same'being centrally formed with an opening 3, and'attached to theoppo ite faces 1 of the said rounded end 2 ate'ratchet wheels 3 and 4,the same having their teethbeveled in opposite directions, and arrangedupon the oppositefaces of the shank of the wrench are spring presseddogs 6 and 7 respectively, one of which normally engages with one of theratchet wheels and also arranged. upon the shank of'the said wrench is arevoluble dog actuating member 8, the

same when swung in one direction, contacting with one of the dogs tobring itstooth out of engagement with one of the ratchet wheels and whenmoved in a second direction, contacts with the other dog to bring thesame out of engagement with its'ratchet wheel, while still moved inanother or neutral\position contacts with both of the dogs to bring thesame out of engagement with each of the ratchet wheels. 1

In order to permit of the operator of the Wrench obtaining a greateramount of leverage I have arranged upon the-shank or handle 1 alongitudinally movable auxiliary shank or shank extension 10 which, byreference to the drawings, it will be noted, can be slid upon the shankproper to extend or lengthen the handle of the wrench.

Secured to the rounded enlarged extension of the shank 1 is a headmember 11 of the wrench, the same being provided with an opening whichco-incides with the openlngs arranged in the said member 2 of the shankas, well as in the ratchet wheel connected with the shank. Pivotallsecured, as at12, to one of the\ends of'the head 11 is a pairof'arms 13and 14 respectively, each of the said arms being centrally formedwith'ztn inturned portion or boss 15 to whicizh is p wetally secured thebifurcated ar provlded upon the lnner faces of the jaws 17 and 18respectively, the said jaws being disposed opposite the openings in thehead,

shank and ratchet wheels, and the inner faces of the said jaws areserrated or otherwise roughened. The free ends of the arms are providedwith links 17 and 18 respec tively, the ends of the links beingpivotally other to contact with or to release an elefment such as a nut22. Thedevice is especially useful when employed in connection'withcarriage nuts, as the said nut may be handled by the jaws after beingremoved from the spindle of the axle to permlt of the removal of theWheelfrom the said spindle and the application of a lubricant thereto,and the necessity of the operator contacting the nut and so soiling hisfingers will be prevented.

Having thus described the invention, What I claim is:

1. In a wrench, a handle member or shank, a longitudinally movableelement associated with the said handle or shank, ratchet Wheels securedto the opposite faces of the shank at one of the ends thereof, springpressed dogs secured to the shank and coacting with the ratchet wheels,a dog operating member adapted to co-act with either of the dogs to movethe same into or out of engagement with its respective ratchet Wheel, ahead for the wrench, pivoted arms upon the head, jaws pivotally securedto the arms, and means for actuating the arms to bring the jaws towardor away from each other.

2; In a, wrench of the class described, a shank provided with a head,arcuate arms pivotally connected with each other and with the head,swinging jaws upon the arms, and means carried by the head and co-actingwith the arms for swinging the arms upon their pivot to bring the jawstoward or away from each other.

3. In a wrench, a handle, a head, oppositely disposed arcuate armshaving one of their ends pivotally secured to one of the ends of thehead, jaws pivoted to the arms, links connected with the free ends ofthe arms, aqmember pivotally connected with the links, and an adjustingmember carried by the head and co-actin'g with the contact member.

.4. In a wrench, a shank, a head, two ,pivotally secured arms connectedwith the head, swinging jaws connected with the arms and extendinginwardly of the head, links pivotally secured with the free ends of thearms, a connecting member-for the links, and a screw member carried bythe head and having a swivel connection with the said connecting memberof the links, as and for the purpose set forth.

In testimony whereof I aifix my signature in presence of two witnesses.
